This invention relates to machines for use In making blscuits, lozenges and the l ke.

Among other ob ects, the invention 1s 1ntended to provide improved means for con-.-

trolling the positioning ofthe products on receiving means.

The-character of the invention will be best understood by reference to one form of biscuit-cutting and panning machine containing an embodiment of the invention which is shown' fonillustration in the accompanying drawings. i

Theillustrative machine is of the type described in patent to GreenNo. 1,292,311, January 21, 1919, in which biscuits are cut or died out from a continuouslymovingdough sheet and are deposited periodically on con tinuously moving pans by alternately retreating and advancing the delivery end of the dough'apron, or of a separate delivery apron forming in efiect a continuation of the dough apron, so as alternately to shorten and lengthenthe supporting surface of the: apron and therebv withdraw such surface from beneath the biscuits to drop them into i the pans. 'With this arrangement, the pan skipping function, i. e. periodic acceleration or other regulation of the panspeed to enable the biscuit depositing to skip the edges.

panner b 1 indicates the dough-sheeting rollers; 2 the dough apron; 3 the biscuit cutter; 4 the ades; and 5 the pan carrier. The dough apron, which conveys the sheet of dough from the rollers to the cutter, is

driven from the continuously driven drum 2, passes over the cutter bed 3, and, in this mstance, continues to and around the pan-' ner blade, "thence returning around suitable guiding and tensioni-ng rollers to the driv-, 1n drum2. l W

'xcept that the doughapron is-thus continuous as a delivery apron around the panof adjacent pans, is effected by movementof the pan carrler (at alternating different ner blade, and except in certain other -features pertaining to the depositingan'd mng mechanism, as hereinafter descru the diagram in Fi 4 is'intended to repre ,v

substantially the same general orgamzation, various functioning,

parts, accessories and operating-mechanism described in said Patent, No. 1,292,811;

though it will be understoodthat thesame,

exemplifies cooperating feeding, forming and 'receivin making biscuits or other articles to which the present invention or features thereof maybe ap licable; i

s described in said patent, the biscuit cutter 3 reciprocates' vertically, and, with its cutter bed 3, is moved horizontally back means of any machine for and forth, moving forward in unison with the feed of the dough sheet while performing its cutting operation.

. The biscuits, as they are out, are fed continuously forward by the a ron, the scrap A being automatically remove by a suitable scrap carrier (not shown), andithebiscuits are periodicallydischarged-by the pan-full from the deliveryend ofthe apromltwhich,

as stated, is alternately shortened and extended for that purpose, eachl retreat gai .ing a number of biscuits to drop successive- Ill) 1y upon then pan. The retreating and advancing movement of the panner blade are.

accom anied by likemoveme'nts ofa takeup rol er 4, around which the lower run of the apron is looped, so as to take up andadvanced at. the same speed that the apron g feeds forward, it is only necessary to retreat it a distance of one-half the length of the batch of biscuits to. be de osited, or for a distance of approximate y half' a pan length; the combined effect of the continuousforward feeding of the apron, retreating of the panner blade and continuous pan feed being to deposit the successiverows of biscuits on the entire length of a pan,- .with the exception of desired margins at the ends of the pan.

The rate of movement of the pans, though moving at alternately difierent speeds, is such as to carry a pan past the foremost position of the delivery end of the apron durin the retreat and advance of the pan ner b ade and to present the next pan in 'proper positionat the time of the succeed--- in retreat of the panner blade. an

hepan carrier 5, in the form herein illustrated, comprises a pair of endless chains running around the carrier-shaft sprocket wheels or guides 5" and provided at inter-'- vals corresponding to the pan lengths with pan-en aging lugs 5". Saidchains are com tinuous y driven from driving sprocket wheels 6 and are guided between the latter ,and'the carrier-shaft sprockets by suitably arranged tensioi'iing and guiding. sprocket wheels 7, 8 and 9.' Y

" Obviously either of the carrier chains naytypify' a drivenchain or its equivalent ,of a" carrier or pan feeding 'device' in which the pans are carried otherwise than bytl e chain or chains itself. 1

As in the former Green patent machine, the pan carrier derives its motion from the cutter-operating crank shaft '10 (Fig. 4') through a set of speed-change gears 11, whereby the carrier maybe ad usted to anyv predetermined speed for the product to be produced, or, in other words, adjusted to suit the speed of the dough apron and frequency of operation of the cutter. The driving train from the cutter-operating shaft 10 to the shaft 12 of the speed-change gears,"

partially shown in Figs. 1 and 2, is the same as in said Patent No. 1,292,311.

From the shaft 13 of the speed-change gears, motion is communicated to the cal? rier-driving sprockets 6 by the sprocket.

wheel 14 and sprocket. chain 15 engaging sprocket wheel 16 on shaft 17 of the car: ieidriving sprockets 6. The-sprockets refeired to are fast on their respective shafts. Thus,

in the illustrative machine the transmission or driving train from the cutter-operating mechanism'to the pan carrier is positively geared with the latter and will always drive the carrier driving sprocket "wheel 6 at Ia constant speed, such speed being determined by proper selection of the speed-change gearslll.

F To'accomplisli the pan-skipping and ad'- justing functions, notwithstanding 'such positivedrive of the". pan-carrier chains ing place. In" the illustrative machine, the

adpisting means for this purpose com rises the guiding and tensioning sprockets I and 8, around which opposite portions. of the chains are looped, the said sprockets being shiftable for letting out and simultaneously drawing in the chains at opposite sides of the carrier driving sprocket ,6, with the con-] sequent efi'ect of relatively moving the upper run of the'chaim; Thus" if the sprockets and 8 are shifted in one direction the movement of the ans will be accelerated,

and if shifted in t e opposite direction the movement will be retarded, I

.The shafts 7* and 8 of said carrier-adjust ing and 8' slidable in guide openings in the side frames of the machine; and the shafts carry loosecollars connected by turn-buckles 18. whereby the shafts with. the respective sprocket wheels 7 and 8 are coupled for movement in unison. By means of the turnand adjusted to maintain upon the carrier chains.

sprockets arefijournaled' in bearings 1" For automatically periodicallyv operating! these chain-adjusting sprockets .to

roduce. ,an ntermittent pan skip, or.) a ternate changes of pan speed, the-.ctilizipled sprocket shafts 7" and 8. are connec withja panskip' actuator, herein typified. by a cam 20 on shaft 19-which is driven from the shaft 13 ofthe speed-change ars 11 by-the intermeshing gears 21 and pan-skip actuator being'tlius properly synchronized with the driving train of the pan carrier;

In the construction f.shown, .the cain ;-20;.co-

22 the said cam or operates with a follower roller 23 mounted in a brackst 2 secured to a. rod 25, one en of Wl110h 18'8l1d8.bl8 in a guide in a crossmember 26 of the machine frame while the other end is attached as hereinafter described to a yoke 27. The rod 25 may be held from turning-by means of a spline or feather key 26 in its guide; 26 as shown in Fig. 5. "A spring 25'. may be arranged between the '10: buckles the shafts may be properly aligned proper tension guide 26 and a collar on the rod 25 to maintain the follower roller in place against the cam, though the spring is not essential as the pull of the pan carrier chains will maintain the follower against the cam.

The-yoke 27 isprovided with bearings for skipping effect is accomplished by feeding the pans at alternating different speeds, one during the discharge and the other during the intervening periods, as explained in said' Patent No. 1,292,311. For this purpose the cam 20 may be of the type described in said patent, i. e. a heart-shaped cam the crosssectional contour of which comprises two opposite spirals of Archimedes, which in coacting with the follower will shift the coupled carrier-adjusting shafts and sprockets at a uniform rate. The carrier being continuously drivenand the action of the cam being gradual, the transition from one pan speed to the other will be consequently gradual as is desirable in this character of hiscuit depositing mechanism.

I The cam 20 is of varying radius lengthwise of its shaft. giving it a general oblique form, and is axially adjustable relative to the follower 23 for varying the cam throw and extent and rate of movement of the car- 'rier adjusting sprockets 7 and 8. as may be required, dependent upon such conditions as the size of products and desired number of rows and the disposition of the same on the pans, etc. The central portion of the cam is concentric with the shaft, and when the follower roller 23 is engaging this central portion there will be no reciprocation of the sprockets 7 and 8, hence the pan carrier will then move continuously at uniform speed. But when the cam is'moved endwise from its neutral pos tion, it will oscillate the follower and thus impart a reciprocation to said sprockets 7 and 8, the movement in one direct on causing an acceleration of the pan speed and the movement in the opposite direction retarding the speed. Thus according to requirements. the cam may be adusted to cause depositing of successive rows of products indefinitely at. uniform spaces apart on receiving surfaces. or to cause periodic spacing! between batches.

For axially adjusting the cam, the shaft 19 on which the cam is rigidly mounted is adapted to be moved endwise by turning the hand wheel 28. Said hand wheel has a long hub 29 formed with a collar at each end and mounted in a bearing in one of the main side 'endwise when the hand wheel is turned independently on said shaft. Normally, however, the shaft and hand wheel turn together, the hand wheel being latched non-rotatably to the shaftby the latch 28" engaging a slot 28* in the shaft. Said latch may be released when the hand wheel is to be turned for adjusting the shaft.

The gear 22 at the opposite end of the shaft 19 has a' hub similar to that of the hand wheel 28, and likewise mounted in a bearing in the opposite side frame, so as to prevent lateral movement of said gear 22; and the shaft 19 is slidable in said gear by'a long spline or feather key so as to permit its endwisemovement through the gear.

As shown in Figs. 6 and 7, the two heart shaped portions of the cam at opposite sides of its concentric middle portion are alike in shape but reversed in position. This construction renders it possible. in connection with an alternately advancing and retreating panner blade,ieither to accelerate the pan carrierwhile depositing the biscuits upon the pan or, if desired, to retard the movement of the pan carrier relatively dur-. ing such delivery and accelerate it while the panner blade is advancing.

In some cases it is desirable to place the biscuits on the pans at greater spaces apart than the spaces at which they'are cut on the dough apron. For instance. I in cutting dough bars (composed of superposed strips of dough) into sections by a straight knife cutter. it is necessary that these sections or cakes be separated upon the pain a substantial distance anart to prevent them from running together by the naturalspread of the dough in the process ofbaking. Such increase of spacing may be accomplished by relatively speeding'thep'an during the de positing. Assume, forexample, that dough bars are cut into sections of two inches. and

that it is desired todeposit twelve rows of such sections on a pan say of thirty-seven inches length. The combined length of the twelve sections will be twenty-four inches.

The dough apron will move forwardin unison with the panner blade twelve inches, and will move forward another twelve inches during the retreat of the panner blade. Duravoid breakage and often. desirable to speed the dough a ron relative to the frequency of operationo the cutter, so as to leave intervening portions of the scrap of such size and strength as to preserve the integrity of'the scrap sheet while being automatically removed by the scrap carrier. It therefore becomes desirable to reduce this spacing when the goods are'placed upon the pan so as to effect economy in placing more goods upon a given surface. Thus goods occupying say forty-two inches on the apron may have to be placed upon a pan of thirty-seven. inches length. Accordingly, the pan speed should be relatively reduced during the depositing of the biscuits. 7

Under the condition first stated,in which twenty-four inches of products are to be spread on a thirt -seven inch pan, the pan speed will be accelerated during the depositing of the biscuits and relatively retarded during the intervening periods while the panner blade is advancing, though at all times movingfaster than the apron. Under the-second stated condition, where batches of products occupying forty-twoinches on the apron are to be placed on the same length pans. the pans will move at a slower rate than the apron during the depositing of the biscuits and at a considerably acceleratedrate during the intervening periods. Again, under ordinary conditions, where the biscuits are to be placedon the pans at the same spacing at which they are cut, the pans will move at the same speed. as the dough apron during the depositing and at a slightly accelerated speed while the panner blade is advancing. The desired conditions are established by adjusting the pan speed through the speed change gears 11, and by adjusting the cam 20 axially to produce the desired alternating pan, speeds and have'the acceleration occur at the period required. Whatever the conditions may be, assuming the position of the pans on. the carrier to be in proper registry with the cam action, the pans will be successively presented to receive the first and subsequent biscuits in proper positions, producing the desired pan skip or the equivalent efiect.

For relatively adjusting the skip actuator and pan carrier to register the pans with the pan skip, or for the equivalent function in the illustrative machine of setting the pan carrier relatively forward or back so as to insure in correlation with the cam action proper presentation of the pans to centralize the batches of biscuits thereon, the connection between the cam follower 23 and yoke 27 is rendered adjustable, such adjustment being accomplished in this instance by inde pendently shifting the sprockets 7 and 8 during the motion of the carrier to effect the-desired relationship of the pan carrier lugs to the delivery end of the apron in correlation with the action o fthe cam. For this purpose the rod 25 carrying the cam follower is screw-threaded through a bevel ear 30 in mesh with a bevel gear 31 whic is journalled in a bracket arm 32 of the yoke' wheel 35. mounted in one'of the main side frames as shown more clearly in Fig. 7. By means of said hand wheel 35 the bevel gears may be operated during the runningl of the machine either to shorten or lengt en'the distance between the camfollower 23 and yoke 27, such adjustment moving the yoke and consequently the sprockets 7 and, 8 and effecting a momentary acceleration-or retardation of the pan feeding run of the pan carrier such as may be required to adjust the latter to proper relationship with the periodicity of the skip action.

B the aforesaid construction, the same results are obtainable as to graduall alternating the panning speeds and re atively adjusting the pan carrier, though positively connected with a continuously driven constant speed driving train, as are obtainable in said Patent No. 1,292,311 b the pan skipping differential interposed in the driving train and its associated adjusting means.

The mechanism for alternately advancing and retreating the delivery endof the dough apron may be of the type described in patent to Green No. 1,291,844 dated January 21, 1919, an important feature of which is provision for varying. the extent of retreat of the panner blade in accordance with the size and number of rows of biscuits to be deposited on a pan. Such mechanism is partially represented in Fig. 1, of the drawings,

applied however to a panner blade carrying frame which reciprocates horizontally -without the up-and-down and tilting motions described in said Patent-No. 1,291,844, In this case the panner blade frame 36 is con nected by the side bars 37 with the shaft of the take-up roller 4, journalled in thesliding bearing blocks 38, and said frame 36 is provided at its forward end with rounded bearing shoes 36 sliding on'the main side frames, whereby the panner blade frame is supported for horizontal reciprocation. The

panner blade is hingedat 39 so as to swing downward. Thus as the panner blade retreats it will drag over the pans and deposit the biscuits, and as it advances it will move with the pans. The pan-engaging lugs 5 onthe carrier chains may be in the form of cross-bars'connecting the two chains so as to avoid injuring the dough apron as the lugs pass under and lift the end of the panner lade. Preferably a resilient sheet metal guard 36 is arranged in the frame under the panner blade to protect the apron.

Referring to the operating mechanism, the

panner blade frame 3 6 carries depending brackets 40 in which is'mounted an operating shaft41l Said shaft 41 carries pinio'ns '42 engaging endless racks 43, whereby the operating shaft 41 is caused to travel in an reciprocation the brackets 40 are orbit-like path' and thereby reciprocate the panner blade as explained in said Patent No.' 1,291,844, but in order to avoid raising and lowering the pannel blade at the l1m1ts of ts ,with vertical slots '44 to permit e; shaft 41 tomove up and. down therein. Said opcrating shaft 41; is driven froma: "shaft 45 by chain a'nd sprockt gearing 46, 47 ar ranged to'provide a flexible elbow transmission, and shaft 45 is driven from the carry-- ing driving haft 17 by sprockets and chain 48. In connection with this mechamsm,

means is provided, not shown, for imparting reciprocatory movement to the racks 43 toincrease or decrease the reciprocatory movement of the panner blade, and also adjusting means for regulating the extent of movement of the racks,- whereby the travel ofthe panner blade back and forth may be exactly ing means g neansffor synchronously operattransmission, comprising periodically actuadjusted 1 to conform to, the speed of the dough apron. For more specific description, referencefis made to said Patent No. 1,291,844. j
